The example of Fig. 4 C and Fig. 4 D is in order to explanation, and viewing area 400 is that entity article 420 is compared vertical normal Az along upward deflection of longitudinal axis Ay with the line of viewing area 400 with the relative position relation of entity article 420.Therefore, computing module 340 is according to the perspective view effect of the second relative angle θ b corrected object prototype, produce the tridimensional virtual object 366 among Fig. 4 D, because the deflection of the second relative angle θ b, the tridimensional virtual object 366 that the user is seen by viewing area 400 in this example visual angle up of serving as reasons down will stretch the tridimensional virtual object 366 in the example of Fig. 4 D upward.
The example of Fig. 4 E and Fig. 4 F is in order to illustrate viewing area 400 and entity article 420 relative level distance D s between the two.Computing module 340 is revised the stereo object size of this object prototype (Cubic object) according to relative level distance D s, produce the tridimensional virtual object 366 among Fig. 4 F, when relative level distance D s is healed when far away, user in the example of Fig. 4 F sees that the object of tridimensional virtual object 366 is less, otherwise heal when near as relative level distance D s, 366 of the tridimensional virtual objects that the user sees are corresponding larger.
Among above-mentioned Fig. 4 A to Fig. 4 F, only illustrate the first relative angle θ a, the second relative angle θ b or relative level distance D s one of them when changing, the corrected object prototype also produces the schematic diagram of tridimensional virtual object 366.In the practical application, relative position relation between viewing area 400 and the entity article 420 comprises the first relative angle θ a, both may change simultaneously at least in three factors such as the second relative angle θ b and relative level distance D s, computing module 340 must calculate respectively its variable quantity to produce corresponding tridimensional virtual object 366, comprise the direction that virtual article 366 presents, angle and coordinate position etc. all can be revised, ask for an interview the example of Fig. 4 G and Fig. 4 H, in the example of Fig. 4 G, entity article 420 is positioned at partially upper left distant place, and computing module 340 is considered the first relative angle θ a simultaneously, the second relative angle θ b and relative level distance D s produce corresponding tridimensional virtual object 366 then for the visual angle observed toward the upper left side by the lower right and have less object size.Above Fig. 4 A to Fig. 4 G is way of example explanation this case viewing area 400 and the relative position relation of entity article 420, but in the practical application relative position relation have various possibilities can be by that analogy, and state each example not only and be limited.
In the above-mentioned example, the actual displayed position of tridimensional virtual object 366 is all on the display plane of transparent display 362, changed visual angle far and near with size up and down of tridimensional virtual object 366 according to relative position relation by computing module 340, tridimensional virtual object 366 is visually cooperated with entity article 420, and then reach interaction effect, when the position of entity article 420 changed, the shape size that tridimensional virtual object 366 presents just can change thereupon.
In addition, entertainment display system 300 can further comprise driver module 380, driver module 380 is coupled between computing module 340 and the stereo display module 360, and driver module 380 mainly drives the image effect of each display unit generation stereoscopic vision on the stereo display module 360 in order to the tridimensional virtual object 366 that calculates according to computing module 340.In the example that Fig. 4 A to Fig. 4 G illustrates, shape with single viewpoint illustrative tridimensional virtual object 366, but because user's eyes have certain parallax, corresponding user's left eye and right eye provide respectively two group images with parallax respectively when showing tridimensional virtual object 366 on the stereo display module 360 in the practical application.
See also Fig. 5 A, Fig. 5 B and Fig. 5 C, it is in order to illustrate according among the wherein embodiment of the present invention three-dimensional virtual article being carried out the schematic diagram that two group images of corresponding user's left eye and right eye were calculated and produced to binocular parallax.In Fig. 5 A, illustrated in this embodiment the user in viewing area 400 two respectively the position in different positions, the angle of its observation entity article 420 and tridimensional virtual object 366 is difference (being so-called binocular parallax) to some extent, therefore, after computing module 340 produces the coordinate position of tridimensional virtual object 366 according to relative position relation, driver module 380 can be further according to the left-eye images 366L among binocular parallax generation Fig. 5 B and the right-eye image 366R among Fig. 5 C, to be presented on the transparent display 362.Do the signal explanation with larger parallax among Fig. 5 A to Fig. 5 C, the present invention is not as limit, and formed two group images of binocular parallax only have less gap mostly in the practical application.
As for the stereoscopic display mode can utilize that sequential is separated, light polarization is separated or other various stereo display techniques be passed to the user about two, this people by existing skill is known, and does not give unnecessary details in addition at this.In this embodiment, driver module 380 transmits respectively a plurality of image frames to transparent display 362 according to sequential, and these image frames can be distinguished corresponding left-eye images and right-eye image, reach by this three-dimensional image effect, but the present invention is not as limit.
